The aim of this study was to compare the nutrient and sediment releases from five Irish tillage soils, inclined at 10- 15-degree slopes, under a simulated rainfall intensity 30 mm h(-1) in controlled laboratory study. Using relationship between soil test phosphorus (STP) soils dissolved reactive (DRP) released surface runoff, runoff risk indicator (RDPRI) developed identify STP level for above which there may be potential threat water quality. results indicated that produce P concentrations...
Slurry application with methods such as trailing shoe (TS) results in reduced emissions of ammonia (NH3) compared broadcast using splashplate (SP). Timing the during cool and wet weather conditions also contributes to low NH3 emissions. From this perspective, we investigated whether due improved slurry method timing an increase nitrogen (N) fertilizer replacement value (NFRV). The effects (June vs. April) (TS SP) on apparent N recovery (ANR) NFRV from cattle applied grassland were examined...
Abstract Phosphorus is essential for plant and animal health. The aim was to determine the impacts of P fertilizer on changes in Morgan’s soil test (STP) liveweight gain (LWG) mature beef animals over last 10 yrs (1999–2008) a 40 yr experiment temperate permanent grassland north‐western Europe. There were three original treatments: 0 (P0), 15 (P15) 30 (P30) kg/ha/yr (1968–2008), new treatments same area that started 1999: P0 then kg P/ha/yr (P0‐30), P15 5 (P15‐5) P30 zero (P30‐0). Six plots...
Abstract Mixtures and pure stands of perennial ryegrass, tall fescue, white clover red were grown in a three‐cut five‐cut system southern Norway, at low fertilization rate (100 kg N ha −1 year ). The nutritional quality (annual weighted averages) the dried forage from two‐first harvesting years was analysed. There no significant effect species diversity on crude protein ( CP ) concentration. In system, we found leading to 10% higher concentrations acid detergent fibre ADF ), 20–22% lower...
Abstract Background Genome-wide and clinical studies have linked the 677C→T polymorphism in gene encoding methylenetetrahydrofolate reductase (MTHFR) with hypertension, whilst limited evidence shows that intervention riboflavin (i.e. MTHFR co-factor) can lower blood pressure (BP) hypertensive patients variant 677TT genotype. We investigated impact of this common on BP throughout adulthood hypothesised status would modulate genetic risk hypertension. Methods Observational data 6076 adults...
Reduced appetite with ageing is a key factor that may increase risk of undernutrition. The objective this study to determine the impact innovative plant protein fibre (PPF) products within personalised optimised diet (PD), physical activity (PA) programme, and their combination on appetite, other nutritional, functional clinical outcomes in community-dwelling older adults multi-country randomised controlled intervention trial. One hundred eighty (approximately sixty per trial centre Germany,...
Abstract. 1. Ivermectin is an anthelmintic veterinary medicine, and excreted in the dung of treated livestock a mainly unmetabolised form. known to have toxic effects on beetles, but most studies date been conducted tropical sub‐tropical species. Relatively few laboratory focused specific ivermectin survival development north temperate beetles. 2. In this study, we experimentally investigated effect concentration various life stages two Aphodius beetle Dung was collected from cattle groups...
The role of biodiversity in regulating the stability ecosystem functioning (functional stability) has importance for reliable delivery services. To date, ecological studies that aim to measure function across a range diversity have almost universally used coefficient variation (CV, ratio standard deviation functional response its mean) reaching conclusions. We argue use CV this purpose can lead misleading conclusions on stability. illustrative scenarios show an assessment based is not as...
Abstract BACKGROUND: The relationship between the weed community and soybean ( Glycine max (L.) Merr.) seed yield quality was assessed in two experiments Illinois, USA. In one field different proportions of target weeds Ambrosia trifida L., Amaranthus rudis J. Sauer, Setaria faberi F. Herrm) were sown into experimental plots, other naturally infested with these weeds. composition communities both fields compared to yield, biomass, canopy cover (% protein, oil, relative water content, weight)...
Dietary changes are required to mitigate the climatic impact of food consumption. Food consumption databases can support development sustainable based dietary guidelines (SFBDG) when linked environmental indicators. An improved knowledge base is crucial transition diets, and multiple indicators should be considered ensure this evidence accounts for trade-offs. The current study aimed quantify daily diets across population groups in Ireland. Nationally representative surveys Irish children...
Grass-based milk production is a major contributor to Irish agricultural output. The study characterized the pool using stable isotope ratio analysis of carbon, nitrogen, oxygen and sulphur. Authentic raw samples were collected from 50 farms on five occasions over 13 months. Mean values −27.11, 6.79, −3.27 6.16‰ obtained for δ13C, δ15N, δ18O δ34S, respectively. δ13C reflected high level grass input increased with increasing cereal concentrate feed (P < 0.001). most negative in spring. There...
